head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.

Optimization · Pure Optimization
A 2D sandbox of procedurally generated planets driven by crafting progression.

Optimization · Pure Optimization
Mastering a richly simulated survival world through its layered metallurgy and seasonal farming systems.
Starbound leans Optimization (Pure Optimization); Vintage Story leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Starbound
Light platforming and combat, generous margins
Vintage Story
Combat has deliberate timing; temporal storms add pressure
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Starbound
Procedural NPCs follow simple fixed behaviours
Vintage Story
Drifters and enemies use scripted attack patterns
Vintage Story leans a little harder on variance, though the gap is small.
Starbound
Procedural planets and loot keep early exploration unknown
Vintage Story
World generation and ore veins are hidden and randomised
Vintage Story leans a little harder on optimization, though the gap is small.
Starbound
Gear tiers, farming, and progression routes dominate
Vintage Story
Metallurgy progression and agriculture cycles are deeply systematic
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
